What are mammary glands?

Mammary glands are special bodies that help some animals feed their babies with milk.

Think of them like a milk factory inside your body, and not just for humans! Many mammals, like cows, dogs, and even seals, have them too. These factories work hard when the baby is hungry, making nutritious milk to give them energy and help them grow strong.

Mammary glands are made up of tiny cells that collect food from your blood and turn it into milk. When a baby licks or suckles on the nipple, it sends a signal to the body, telling it to start making more milk, just like how a button might press a machine in a toy.

Having mammary glands is super helpful because it gives babies the best start in life. The milk has all the good stuff they need, like proteins and sugars, to grow healthy and happy. So, even though you might not think about them every day, your body uses these amazing milk factories to keep you strong when you're little!
